i have a 07 R6, a few weeks ago i accidently left the bike on and ignition off and the fan drained all the battery. i jump started the bike and it was fine again. But today when i took my bike out again after a week of no riding, the bike won't start so i jump started it again. After riding for around 20mins to let the bike charge the battery when i got home and stalled the bike, it won't start again!
what is my problem?
should i get a new battery? or a battery charger?
ps. i don't have a voltmeter at home to check the battery level...
